The p that "goes with" an r of .776 is actually closer to .01 than to .05. And would anybody care about a confidence coefficient of, say, 91.3? 10. Covariance vs. correlation. Previous reference was made to the tradition of calculating Pearson's r for two continuous variables whose linear relationship is of concern.

When measured in a population the Pearson Product Moment correlation is designated by the Greek letter rho (ρ). When computed in a sample, it is designated by the letter "r" and is sometimes called "Pearson's r." Pearson's correlation reflects the degree of linear relationship between two variables. It ranges from +1 to -1.

Incidentally, to save time, you should consider purchasing a calculator that can do the more cumbersome calculations (e.g., the standard deviation, Pearson’s r) automatically. Along the same lines, many of you probably have access to computers and statistical packages.

Pearson’s Product-Moment Correlation Coefficient. Also called Correlation Coefficient or ‘ r ’. This is a more precise tool. In summary it is a measure of the tendency of data to lie on a straight line. The value of ‘r’ ranges from -1 to 1 i.e. -1 ≤ r ≤ 1. Following are examples of scatterplots:
